[MICROBA-1109]
* Remove the requirement for the `auto_certificate_generation` waffle switch to be enabled in order for a learner to be eligible for a certificate. This switch should control _when_ a certificate is generated, not _if_ a certificate will be generated for a learner.
* Move the `auto_certificate_generation_enabled` check to happen before we try to generate v2 certificates in signals.py
* Update unit tests
* Update documentation
* Generate common/djangoapps import shims for LMS
* Generate common/djangoapps import shims for Studio
* Stop appending project root to sys.path
* Stop appending common/djangoapps to sys.path
* Import from common.djangoapps.course_action_state instead of course_action_state
* Import from common.djangoapps.course_modes instead of course_modes
* Import from common.djangoapps.database_fixups instead of database_fixups
* Import from common.djangoapps.edxmako instead of edxmako
* Import from common.djangoapps.entitlements instead of entitlements
* Import from common.djangoapps.pipline_mako instead of pipeline_mako
* Import from common.djangoapps.static_replace instead of static_replace
* Import from common.djangoapps.student instead of student
* Import from common.djangoapps.terrain instead of terrain
* Import from common.djangoapps.third_party_auth instead of third_party_auth
* Import from common.djangoapps.track instead of track

* Add empty common/djangoapps/__init__.py to fix pytest collection
* Fix pylint formatting violations
* Exclude import_shims/ directory tree from linting
Because of the way async tasks pass arguments, we were passing in a string of a dictionary
that contained the id verification status but checking it against a dictionary in the
task's function, which was causing errors for generating certificates for passing users
whose id verification status changes to approved after they are passing.
This reworks what was done #17930, since it had to be reverted from the IDVerificationAggregate migration.
We decided to abandon that model and directly read from both id verification models.
This partially reverts commit ee1c3a4548.
The migration files introduced by the commit have been kept since they have been run
already on several enviornments.
